According to several local reports, Apple is currently considering building a new data center in Nevada. KRNV & MyNews4.com reported today that Apple representatives attended a Washoe County Commission meeting to discuss plans to invest $1 billion over 10 years and build a new data center at the Reno Technology Park:

News 4’s Ben Briscoe is at the Washoe County Commission meeting, where Officials from Apple are speaking to commissioners… Mary-Sarah Kinner, the Press Secretary for the Governor’s Office confirms to News 4 the Governor’s Office of Economic Development is involved in the deal to bring Apple to Northern Nevada.

The report claimed Apple said it plans to begin construction in August and hopes to finish by the end of 2012. Although the Governor’s Office apparently estimated the project would result in over 300 jobs and 500 construction jobs, the Washoe County School Board and the Reno City Council still have to sign off on the deal. Mynews4.com reported the City of Reno is expected to make a decision at tomorrow’s council meeting. Apple already operates its own data centers in Maiden, N.C., and it recently announced plans to expand at the location and on 160 acres of land it purchased in Prineville, Ore.
